SCROLLING THROUGH SETUP-LEVEL
Selection of function-group and function:
SETUP is divided into several function groups and functions.
Each function has a unique number, which is displayed below the word "SETUP" at the bottom of
the display. The number is a combination of two figures. The first figure indicates the function-group
and the second figure the sub-function. Additionally, each function is expressed with a keyword.
After selecting a sub-function, the next main function is selected by scrolling through all "active" subfunctions (e.g. 1, 11, 12, 13, 14, 1, 2, 3, 31 etc.).

EXPLANATION OF SETUP-FUNCTIONS
1 - PRESET
MEASUREMENT UNIT
11
SETUP - 11 determines the measurement unit for preset, total,
accumulated total and pulse output. The following units can be selected:
L - m3 - kg - lb. - GAL - USGAL - bbl - _ (no unit).
DECIMALS
12
Alteration of the measurement unit will have consequences for operator
and SETUP-level values.
Please note that the K-factor has to be adapted as well; the calculation is
not done automatically.
The decimal point determines for preset, total and accumulated total the
number of digits following the decimal point.
The following can be selected:
0000000 - 111111.1 - 22222.22 - 3333.333
K-FACTOR
13
With the K-factor, the flowmeter pulse signals are converted to a quantity.
The K-factor is based on the number of pulses generated by the
flowmeter per selected measurement unit (SETUP 11), for example per
cubic meter. The more accurate the K-factor, the more accurate the
functioning of the system will be.
Example 1:
Calculating the K-factor.
Let us assume that the flowmeter generates 2.4813 pulses per
liter and the selected unit is "cubic meters / m3". A cubic meter
consists of 1000 parts of one liter which implies 2,481.3 pulses
per m3. So, the K-factor is 2,481.3. Enter for SETUP - 13:
"2481300" and for SETUP - 14 - decimals K-factor "3".
Example 2:
Calculating the K-factor.
Let us assume that the flowmeter generates 6.5231 pulses per
gallon and the selected measurement unit is gallons.
So, the K-Factor is 6.5231. Enter for SETUP - 13: "6523100"
and for SETUP - 14 decimals K-factor "6".
DECIMALS K-FACTOR This setting determines the number of decimals for the K-factor entered.
(SETUP 13). The following can be selected:
14
0-1-2-3-4-5-6
BATCH MAXIMUM
15
Please note that this setting influences the accuracy of the K-factor
indirectly. (i.e. the position of the decimal point and thus the value given)
This setting has NO influence on the displayed number of digits for total
(SETUP 12)!
This function limits the operator to enter a new preset-value which is more
as the entered batch maximum.
MS3920314004
Page 14
2 - OVERRUN
Overrun can occur at the end of the batch process, as a result of slowness of a valve / pump.
Consequently, the accuracy is less. With this function, the ERB analyses the actual overrun
characteristic after every batch. This information is used to correct the overrun automatically.
For an accurate overrun correction, it is necessary that the flow meter
OVERRUN
meets certain technical demands, such as "high resolution" and shows no
21
"false" overrun due to a slow update time.
Do not enable this function if the flow meter does not meet these technical
demands.
The overrun characteristic of the system will be analyzed during a certain
OVERRUN TIME
time after the batch. In this way, false signal generated through leakage
22
are eliminated.
Enter here the expected time needed by the system to stop a batch. It is
advisable to provide extra time in order to avoid an incorrect overrun
correction or false leakage alarms.
Note that the next batch can only be started after elapsing of this overrun
time!
The minimum overrun time is 0.1 second, maximum 999.9 seconds.
3 - DISPLAY
The large 17mm digits can be set to display the actual batched quantity
DISPLAY
(increase) OR to display the remaining quantity to be batched (decrease).
31
The functions below will only effect the optional LED-backlight.
If a LED backlight has been supplied, the color can be selected.
BACKLIGHT
Following selections are available:
(OPTION)
32
OFF - GREEN - AMBER
The density of the backlight can be set in the range: 1 - 5
BRIGHTNESS
(OPTION)
One is minimum and five is maximum brightness.

MS3920314004
Page 15
4 - POWER MANAGEMENT
When used with the internal battery option, the user can expect reliable measurement over a long
period of time. The ERB has several smart power management functions to extend the battery life
time significantly. Two of these functions can be set:
The calculation of the display-information influences the power
LCD NEW
consumption significantly. When the application does not require a fast
41
display update, it is strongly advised to select a slow refresh rate.
Please understand that NO information will be lost; every pulse will be
counted and the output signals will be generated in the normal way.
The following can be selected:
Fast - 1 sec - 3 sec - 15 sec - 30 sec - off.
Example 3:
Battery life-time
coil pick-up, 1KHz. pulses and FAST update: about 2 years.
coil pick-up, 1KHz. pulses and 1 sec update: about 5 years.
BATTERY-MODE
42
Note: after a button has been pressed by the operator - the display
refresh rate will always switch to FAST for 30 seconds. When "OFF" is
selected, the display will be switched off after 30 seconds and will be
switched on as soon as a button has been pressed.
The unit has two modes: operational or shelf.
After "shelf" has been selected, the unit can be stored for several years; it
will not count pulses, the display is switched off but all settings and totals
are stored. In this mode, power consumption is extremely low.
To wake up the unit again, press the SELECT-key twice.
5 - FLOWMETER
The ERB is able to handle several types of input signal. The type of
flowmeter pickup / signal is selected with SETUP 51.
Note: The selections "active pulse" offer a detection level of 50% of the
supply voltage.

SENSOR SUPPLY
Terminal 3: sensor supply 1.2V - 3.2V:
Terminal 3 provides a limited supply voltage of 3.2 V DC (coil signals 1.2V) for the signal output of
the flowmeter.
Note: This voltage MAY NOT be used to power the flowmeters electronics, converters etc, as it will
not provide adequate sustained power ! All energy used by the flowmeters pick-up will directly
influence the battery life-time. It is strongly advised to use a "zero power" pickup such as a coil or
reed-switch when operating without external power. It is possible to use some low power NPN
output signals, but the battery life time will be significantly reduced (consult your distributor).
Terminal 6: sensor supply 8.2V:
With this option, a basic but real sensor supply of max. [email protected] is available to power e.g. a hall
sensor.
REMARKS: TERMINAL CONNECTORS:
Terminals 1-3; Flowmeter input:
Three basic types of flowmeter signals can be connected to the unit: pulse, active pulse or coil. The
screen of the signal wire must be connected to the common ground terminal
The input signal type has to be selected with the correct SETUP-function (read par. 3.2.3.)
Pulse-signal NPN / NPN-LP:
The ERB is suitable for use with flowmeters which have a NPN output signal. For reliable pulse
detection, the pulse amplitude has to go below 1.2V. Signal setting NPN-LP employs a low-pass
signal noise filter, which limits the maximum input frequency - read par. 3.2.3.

MAINTENANCE
5.1.
GENERAL DIRECTIONS




Mounting, electrical installation, start-up and maintenance of the instrument may only be
carried out by trained personnel authorized by the operator of the facility. Personnel must read
and understand this Operating Manual before carrying out its instructions.
The ERB may only be operated by personnel who are authorized and trained by the operator
of the facility. All instructions in this manual are to be observed.
Ensure that the measuring system is correctly wired up according to the wiring diagrams.
Protection against accidental contact is no longer assured when the housing cover is removed
or the panel cabinet has been opened (danger from electrical shock). The housing may only
be opened by trained personnel.
Take careful notice of the " Safety rules, instructions and precautionary measures " in the front
of this manual.
The ERB does not require special maintenance unless it is used in low-temperature applications or
surroundings with high humidity (above 90% annual mean). It is the users responsibility to take all
precautions to dehumidify the internal atmosphere of the ERB in such a way that no condensation
will occur, for example by placing dry silica-gel sachet in the casing just before closing it.
Furthermore, it is required to replace or dry the silica gel periodically as advised by the silica gel
supplier.
Battery life-time:
It is influenced by several issues :




Type of sensor: read chapter 3.2.3. NPN and PNP inputs consume more energy than coil inputs.
Input frequency: the higher the frequency, the shorter the battery life-time.
Display update: fast display update uses significantly more power; SETUP 41.
Low temperatures; the available power will be less due to battery chemistry.
Note: It is strongly advised to disable unused functions.
Check periodically:
 The condition of the casing, cable glands and front panel.
 The input/output wiring for reliability and aging symptoms.
 The process accuracy. As a result of wear and tear, re-calibration of the flowmeter might be
necessary. Do not forget to re-enter any subsequent K-factor alterations.
 The indication for low-battery.
 Clean the casing with soapy-water. Do not use any aggressive solvents as these might damage
the coating.

APPENDIX B:
PROBLEM SOLVING
In this appendix, several problems are included that can occur when the ERB is going to be installed
or while it is in operation.
Flowmeter does not generate pulses:
Check:
 Signal selection SETUP - 51,
 Pulse amplitude (par. 4.4.),
 Flowmeter, wiring and connection of terminal connectors (par. 4.4.),
 Power supply of flowmeter (par. 4.4.).
Flowmeter generates "too many pulses":
Check:
 Settings for total: SETUP 11-14,
 Type of signal selected with actual signal generated - SETUP - 51,
 Sensitivity of coil input - SETUP - 51 and par. 4.4.
 Proper grounding of the ERB - par. 4.4.
 Use screened wire for flowmeter signals and connect screen to terminal 9. (unless connected at
sensor)
The pass code is unknown:
If the pass code is not 1234, there is only one possibility left: call your supplier.
ALARM
When the alarm flag starts to blink an internal alarm condition has occurred. Press the "select
button" several times to display the 4-digit error code. The codes are:
0001:
0002:
0003:
irrecoverable display-data error: data on the display might be corrupted.
irrecoverable data-storage error: the programming cycle might have gone wrong: check
programmed values.
error 1 and error 2 occurred simultaneously
The alarm condition will almost certainly be handled internally and if all mentioned values still appear
correct, no intervention by the operator is needed. If the alarm occurs more often or stays active for
a longer time, please contact your supplier.
